iMac pre 2012 Mojave Support
*I know how to google, if the only advice you can provide is from the 1st google page please move on.
So I have a iMac Mid 2010, fitted with 16GB of RAM, an SSD, an HD 5670 512mb, and now an i5 680 (and a blu-ray drive!).
I also have a compatible wifi/bluetooth 4.0 card lying around, but I didn’t install as it is a solder-job (and this is my family’s computer).
So, my real question is, why can’t my machine run Mojave?
The only thing I have found, is that my GPU doesn’t support metal.
So, I have found a cheap mxm graphics card, HD 7650a 2GB, that apparently is supported (as it is a 7000 series AMD card). If you can verify compatibility, please do.
If I flash this card to Apple’s firmware, and use a Mojave patch tool, will this machine see any issues running the latest OS?
I know we are still in the Beta stages, but surely someone knows more than just a list of compatible Macs, what’s the REASON behind them being compatible?
EDIT (12/16/18): I am surprisingly disappointed no one has tried this yet. As far I know, the latest and greatest consumer MXM graphics cards from both the Red and Green Teams are the RX 580 and the GTX 1080.
Unfortunately, as my machine is the 21.5”, a full MXM card will not fit, only the half size. I know 3rd party patches exist for graphic cards to work with Macs, and AMD is better supported.
So fine, I will buy this HD 7650a and attempt to patch it and run it in my iMac, then maybe the misinformation, dated theory, and “You can’t”s will finally cease.
